ADJUSTABLE FLUE CONNECTi Filed March 7, 1952 Patented July 25, 1933UNITED STATES ANTON yuzaxrovrrorr, or rrr'rsBUneH, PENNSYLVANIA f aADJUSTABLE BLUE CONNECTION Application filed. March 7, 1932. Serial No.597,335.

This is a continuation in part of my companion application Serial No.583,629, filed December 29, 1931, and represents a construction adaptedfor the purposes set forth in that application but which is simpler,less expensive and of greater versatility.

In general the objects and advantages of the present invention arebasedupon those set forth in my aforesaid companion application but thepresent invention offers even further advantages due to itsconstruction.

Such other or additional objects and-advantages will either be apparenthereinafter or will be pointed out as this description 16 proceeds. v I

In the accompanying drawing, I have illustrated features of the presentinvention, and in such drawing:

Figure 1 is a perspective view of a simplifiedformof the presentinvention.

Fig. 2 is a front view showing the device in operative association witha fragment of brickwork in which it is ordinarily embedded.

Corresponding numerals designate similar parts throughout the severalviews of the drawing:

of my invention is generally embedded in brickwork 10 or the like, afragment of which is shown in Fig. 2 and more detailed- Referring to thedrawing, the construction proof material. This ring may be made otherthan by casting if so desireddepending upon the material used andfhenceits characteristics and may be of any suitable diameterand wallthicknessas explained in my aforesaid application. t V Whatever the precisedimensionsor material, the ring 11 is provided with diametricallyopposite socketed plates, each composed of a metallic rectangular platemember 12 riveted, welded or otherwise suitably secured to the exteriorof the ring 11 and theseplates are preferably contoured to thecurvatureof the ring so that a snug, firm fit is secured. Extending atright'angles from these plates 12 are the metallic bosses" or extensions13, preferably integral with the plates, said bosses or extensions beingtapped outand suitably interiorly threaded for a purpose to behereinafter explained. As is apparent from Fig. 2, the plates and bossesbecome em bedded in the brickwork 10 preventing any angular rotation orother movement of the ring when once positioned. Said ringis alsoprovided with diametrically opposite apertures 14 which register withthreaded bosses 13 on plates 12 aforesaid.

Screw-threaded bolt members 15 are provided as shown and in practicethese are screwed into the bosses 13' passing through apertures 14 andthese apertures 14, arepurposely made at least slightly larger than thethreaded bolts to providefor free. and easy access of the bolts. to thethreaded bosses and for equally simple withdrawal when required.

. These bolts are of suitable length and preferably extend toward-eachother leaving only a relatively small free space betwen them.

As will be understood. from the foregoing and from the aforesaidcompanion application, the invention is adapted to accommodate stovepipes of varioussizes and at, various. angles and positions. Forthlsreason, the

ring 11 is made at least slightly largerinrliameter than the largestdiameter of stove.

pipes used and the bolts l5- -ext'en'dj-toward each other farenough sothat stove pipes-of minimum diameter can be accommodated;

The rear edge of the stove'pipe- 11a ispref" erably recessed or. slottedas at 16 sothat,--the ii-ti bolts being in position, the stove pipe canbe positioned with the bolts in the slots 16.

Previously, washer members 17 of suitable metal or fireproof materialare threaded on the bolts so that when the stove pipe end is positionedon said bolts the washers can be moved until they snugly rest againstthe elite rior of the stove pipe section. These washers are suitablemetal disks of appropriate size and having a central aperture 18 screwthreaded interiorly at 19 for use on said bolts. As shown in Figs. 2, 4and 5, said washers may be provided with spaced peripheral notches orrecesses 20 so that if desired tor necessary a tool can be inserted inany of said notches or recesses to turn said washers into tighter orlooser positions.

When the stove pipe has been assembled on the bolts and the washers 17snugly positioned against the stove pipe, suitable nuts such as wingnuts 21 are positioned on the bolts against the inside of said stovepipe section 11a and these are tightened until the whole assembly isfirm and relatively rigid, intermediate Washers 22 being generallyemployed for the usual purposes.

As shown in Fig. 3, the bosses 13 may be interiorly tapered toward theirouter ends as at 23 so that bolt 15 abuts against the end of the bossand wedges itself in position preventing movement of the bolt too farand thus wasting a portion of the bolt length although such excesspositioning would dono other harm.

i Fig. 6 illustrates a construction which is identicai with Fig. 4 of myaforesaid companion application except that the spacer 26 which may beused between the stove pipe section 18' and the ring 11, as clearly setforth in said application, as interiorly screw threaded thus making amore mobile yet firm and adaptable construction. In 6, 21 represents ascrew-threaded bolt having, an enlarged head 23, spacer 26 0f suitablemetal beingso chosen as to size, that it substantially completely fillsup the space between ring 11 ands'tove pipe sections 18. The assembly iscompleted by a washer 25 and wing nut 24. Fig. 7 illustrates a metallicspacer 27 internally screw threaded at 27" adapted to be substituted forthe spacer 26 of Fig. 6 when a-stove pipe of larger diameter is used inconnection with the invention.

It will be clear, therefore, that I have provided a modified form ofadjustable flue connection wherein a simpler and more versatileconstruction has been produced. The further advantages are seemed thatthe stove pipe section need not be centered'with respect to the ring 11but in order to meet conditions "in some instancesit will be understoodthat the stove pipe section could be accommodated in a decenteredposition, that is, one in which it would not bBCOllCQIltlIC'tO the ringand this could be clearly accomplished merely by the appropriatepositioning of the washers l7 and wing nuts 21, the arrangement beingmade further possible by the relatively long bolt members 15 thusaffording a wide variety of position and of stove pipe section.

I am not limited however precisely to the above indicated constructionbut may make suitable further or additional n'iodilications,substitutions, variations or omissions without departing from tl espirit and scope of the present invention. and of the sub-joined claims.For example, the doc-entered positioning of the stove pipe section orflue could also be effected .by utilizing unequally sized. spacers. Itis to be understood that the stove pipe or flue section shown is a partof the normal installation and thatit is not furnished as a part of thepresent invention, it being only necessary, in order to install thepresent invention to'r'ecess or slot such stove pipe or flue section soth at it will receive the bolts 15 or the like.
